十字路口车辆穿梭，行人熙攘，车行车道，人行人道，有条不紊。那么靠什么来实现这井然秩序呢？中国的私家车越来越多，走在城市中，酒店，商店的门前排着拥挤的车辆，堵车的现象时有发生，人们只能坐在车中焦急的等待，交通事故时有发生，所以在城市中建立一套完善的交通灯控制系统，十分必要，该系统可以有效的解决以上问题。交通信号灯控制方式很多。本系统采用MSC-51系列单片机。
近年来随着科技的飞速发展，单片机的应用正在不断深入，同时带动传统控制检测技术日益更新。在实时检测和自动控制的单片机应用系统中，单片机往往作为一个核心部件来使用，仅单片机方面知识是不够的，还应根据具体硬件结构软硬件结合，加以完善。80C51单片机是一款八位单片机，他的易用性和多功能性受到了广大使用者的好评。这里介绍的是如何用80C51单片机来实现太原科技大学的毕业设计，该设计是结合科研项目而确定的设计类课题。本系统以设计题目的要求为目的，采用80C51单片机为控制核心，通过74LS138,74LS47等芯片的系统连接，根据实际的电路设置P2口红、绿、黄灯燃亮时间的功能，从而实现交通灯的系统设计。整个系统的电路结构简单，可靠性能高。

Crossroads shuttle vehicles, pedestrians bustling, car lanes, the pavement and orderly. So to achieve the orderly what order? China's growing number of private cars, walking in cities, hotels and shops in front of a crowded row of vehicles, congestion occurred from time to time, people can only sit anxiously waiting cars, traffic accidents occur from time to time, Therefore, in the city to establish a traffic light control system, is necessary, the system can effectively solve the above problem. Many traffic lights control. The system uses MSC-51 series single chip.
In recent years, with the rapid development of science and technology, the application of SCM is at the same time, traditional detection techniques to control the growing update. In real-time detection and automatic control system of single-chip applications, often as a single-chip core component to use only single-chip is not enough knowledge, but also the structure of hardware and software in accordance with
